Semi-continuous Operating Pyrolysis Plant

The BLJ-16 semi-continuous operating pyrolysis plant, with processing capacity 15-20t/d, is developed based on the batch operating pyrolysis plant. It can deal with various kinds of waste materials, such as plastic, tyre, rubber, oil sludge, medical waste etc. Through the semi-continuous plant, the waste can be converted into fuel oil and other end-products. All the end-products are useful resources and have high economic values in the market.

Compared with the batch plant, BLJ-16 has similarities and differences:

Differences:

1. The BLJ-16 plant can work 3-4 shifts per day and its reactor needs to be cooled down before the second batch. It needs only one hour to cool the reactor.

2. It has a small feeding hole, so the materials need to be cut into small pieces. For plastic waste, if the materials’ humidity is higher than 15%, it also a dryer to dispose the waste first. When disposing medical waste, the plant also needs disinfection system and crushing system. The pre-treatment step can make the pyrolysis process more efficient.

3. The feeding of raw materials and discharging of slags are both automatic, which can greatly save manpower and cost.

Similarities:

1. The structure of reactor for the pyrolysis process is 360-degree rotating. This special design makes the bottom of reactor heat evenly, which lengthen the service life of reactor as well as improve the pyrolysis speed.

3. BLJ-16 adopts new type of condensers which has larger cooling area and better cooling effect, so it can improve the oil yield efficiency by 5%. In addition, the catalyst we use is made from 24 chemicals, which can overcome the disadvantage of the traditional boiler with low oil output and bad oil quality.
